The country is known for its extensive droughts, considerable wet periods, dust storms, tornadoes, tropical cyclones, heat waves, bushfires, and frosts. The climate varies across the continent, with arid and semi-arid regions, Mediterranean coastal areas, and tropical zones. Tropical areas in Australia include Darwin, Cairns, Townsville, and Broome, each with its unique characteristics.
Darwin
Darwin, located in the Northern Territory, has a tropical savanna climate with distinct wet and dry seasons. The dry season runs from May to September, with sunny days, mild sea breezes, and low humidity. The wet season, from December to March, brings heavy monsoonal rains, lightning displays, and increased cyclone activity. The build-up in temperature and humidity preceding the wet season is known locally as "the buildup."
Cairns
Cairns, situated on the tropical northeast coast of Far North Queensland, experiences a tropical monsoon climate. Its wet season, from November to May, is marked by heavy monsoonal downpours, while the dry season, from June to October, still sees occasional light showers. Cairns is prone to tropical cyclones and has hot, humid summers and warm winters. The city's proximity to the Great Barrier Reef and the Daintree Rainforest makes it a popular tourist destination.
Townsville
Townsville, a city in North Queensland, is part of the dry tropics region of the state. The city experiences variable rainfall due to the influence of the El Niño–Southern Oscillation. Townsville boasts attractions such as "The Strand," a tropical beach and garden strip, and Reef HQ, a large tropical aquarium showcasing the flora and fauna of the Great Barrier Reef.
Broome
Broome, located in the north of Western Australia, offers a tropical escape with its hot, humid summers and warm winters. Its dry season, from May to October, features warm days and pleasant nights. The wet season, from November to April, brings rainfall, higher temperatures, and humidity, occasionally resulting in local flooding.

Tropical climate in Australia is characterised by distinct wet and dry seasons
Australia experiences a variety of climatic conditions due to its vast size. The country can be divided into six distinct climate groups: Equatorial, Tropical, Sub-tropical, Desert, Grassland, and Temperate. The tropical climate in Australia is characterised by distinct wet and dry seasons.
The tropical zone in Australia includes places like Darwin, Cairns, Townsville, and Broome. The Northern Territory, including Darwin, has a tropical savannah climate with high humidity and two seasons: the wet and the dry. The wet season lasts from October to April, while the dry season spans from May to September. During the dry season, the days are warm and sunny, with average afternoon humidity of around 30%. The wet season is hotter, with temperatures often exceeding 30°C and high humidity.
The transition between the wet and dry seasons is marked by a period of humidity known as the 'build-up'. This period usually lasts for three to four months. The tropical regions of Australia experience a significant variation in rainfall throughout the year. While the dry season sees very little rainfall, the wet season brings torrential rains and an increased risk of tropical cyclones.
The subtropical zone in Australia covers a large central portion of the country. This zone acts as a divider between the tropical and temperate regions. The subtropical ridge, influenced by the movement of warm tropical air, contributes to the arid conditions in many parts of Australia. The southern coastal regions of Australia, including parts of New South Wales, Victoria, Tasmania, and South Australia, fall under the Temperate zone and experience four distinct seasons.
The climate in Australia is highly variable, and the country is susceptible to the effects of the El Niño–Southern Oscillation, which brings seasonal abnormalities. Australia experiences extensive droughts, heatwaves, bushfires, and occasional dust storms and tornadoes. Climate change is a significant issue in Australia, with rising temperatures and increasing desertification.

Tropical cyclones, heatwaves, bushfires, and frosts are associated with the Southern Oscillation
Australia has a highly variable climate, with frequent droughts and wet periods that cause major flooding. The country is one of the most affected by the El Niño–Southern Oscillation (ENSO), a global climate phenomenon that causes seasonal abnormalities. The Southern Oscillation is the atmospheric component of ENSO, causing an oscillation in surface air pressure between the tropical eastern and western Pacific Ocean waters.
The occurrence of ENSO is unpredictable, but it is associated with tropical cyclones, heatwaves, bushfires, and frosts in Australia. During La Niña years, the formation of tropical cyclones shifts westward across the western Pacific Ocean, increasing the landfall threat in China. In contrast, during El Niño events, the formation of tropical cyclones shifts eastward, making Micronesia more likely to be affected. The risk of tropical cyclones in Queensland, Australia, is reduced by 50% during El Niño events.
Heatwaves in Australia are also associated with ENSO. El Niño years generally experience warmer-than-average temperatures, with hotter daily temperature extremes across the south, especially in spring and summer. The warming phase of the sea surface temperature is known as "El Niño".
Bushfires in southeast Australia have been linked to ENSO, with an increased risk of a significant bushfire season following El Niño events, especially when combined with a positive Indian Ocean Dipole event.
Finally, ENSO can also influence frost patterns in Australia. El Niño events can lead to reduced cloud cover, resulting in cooler temperature minima during winter-spring and a longer frost season.

The tropical zone includes areas north of the Tropic of Capricorn
Australia experiences a variety of climatic conditions, primarily due to its vast size. The country can be divided into six distinct climate groups: equatorial, tropical, subtropical, desert, grassland, and temperate. The tropical zone includes areas north of the Tropic of Capricorn, such as Darwin, Cairns, Townsville, and Broome. These regions have a warm and humid climate for most of the year, with distinct wet and dry seasons. The wet season typically lasts from November to March, with temperatures often exceeding 30°C and high humidity. The dry season, on the other hand, occurs between April and October, with lower temperatures and clearer skies. The average temperature during the dry season is around 20°C.
The Northern Territory, including Darwin, has a tropical savannah climate with high humidity and two distinct seasons. The wet season, from October to April, experiences occasional tropical cyclones and heavy rainfall, while the dry season, from May to September, is characterized by warm and sunny days with low rainfall. The Kimberley region in Western Australia also falls within the tropical zone, boasting an extremely hot monsoonal climate with high annual rainfall.
The tropical climate in northern Australia is influenced by the Madden-Julian Oscillation (MJO), which affects rainfall patterns. Tropical cyclones, heat waves, bushfires, and droughts are also associated with the El Niño–Southern Oscillation. Australia's climate is the second driest of any continent, after Antarctica, with 80% of the land receiving less than 600 mm of rainfall annually. The dryness is largely due to the subtropical high-pressure belt, which brings dry air down onto the continent.

Australia's climate varies due to its large size, with six distinct climate groups. The Climate of Australia is the second driest of any continent, after Antarctica. The country is one of the most affected by the El Niño–Southern Oscillation, which brings about seasonal abnormality, extensive droughts, and considerable wet periods.
The six distinct climate groups are Equatorial, Tropical, Sub-tropical, Desert, Grassland, and Temperate. The Temperate zone, which includes coastal regions of New South Wales, Victoria, Tasmania, and most of South Australia, experiences four seasons. Summer spans from December to February, with an average temperature range of 16°C to 26°C. Autumn, from March to May, has a range of 11°C to 20°C. Winter, from June to August, ranges from 6°C to 14°C. Finally, Spring, from September to November, has a temperature range of 10°C to 20°C.
The Tropical zone covers the Top End of the Northern Territory, including Kakadu and Arnhem Land. The Sub-tropical zone includes the coastal and inland fringe along the Queensland coast, with Lady Elliot Island falling into this category. The tropical regions of Australia have distinct wet and dry seasons, with the dry season lasting about six months between April and October. The wet season, from November to March, is hotter and more humid.
The Northern Territory has two distinctive climate zones. The northern end, including Darwin, has a tropical savannah climate with high humidity and two seasons. The dry season, from May to September, is warm and sunny, while the wet season, from October to April, experiences heavy rainfall.
The majority of the state has arid and semi-arid climates. The southern coastal parts have a Mediterranean climate with mild, wet winters and hot, dry summers. The central four-fifths of the state is semi-arid or desert and is lightly inhabited, with mining as the primary activity.
